I was pleased to receive the following notice from Oracle product management in my email box this week:

Hi All,

As you might know, the transition of Corporate Single Sign-On (Intranet and Extranet) to Oracle Access Manager-11g is complete and the first production deployment of OAM 11g with a multi-million user population is now live. Starting Fri, Apr 1st, 2011, OAM-11g is now taking 100% of authentication load from extranet web properties of Oracle without any incident. All customers that access any Oracle service over the extranet like www.oracle.com, OTN, MOS, ARU etc. are now authenticated with Oracle Access Manager 11g.

It makes me feel good to know that we actually use our own products – even the latest version!

The key statistics for the Extranet deployment are actually quite impressive:

• Total user population: 12 M
• Avg daily authentication load so far: 350K users
• Expected peak daily authentication load: 800K users (around special events like Open World)
• Avg authentication latency: 120 milliseconds
• Avg CPU usage: under 5%

Other Highlights:

• This is the first production deployment of OAM-11 with a multi-million user population.
• Like the intranet roll-out, this transition to OAM-11 was done with zero downtime. 
• The gradual/phased ramp-up to 100% load allowed PDIT and dev team to triage problems and fix them before they impacted wider populations.

By the way, I’m not disclosing any secrets.  We were told we could spread this information around!  So have a piece of “virtual” chocolate cake with Fido and me.
